bodiment of the. invention theresubmitted. for illustrative purposes, I have shown a stone working machine, here inthe form of a track channeler supported uponxa carriage or framework 1. The latter is provided at 1ts opposite ends with two transverse shafts flanged truck wheels 3which are adapted to run upon the rails, the latter bein'g customarily laid upon the quarry bottom to permit the advance of the machine when cutting in the usualfa'shion.

The machine is provided with suitable cutting appliances and with actuating means therefor, being herein equipped. for that purpose with a tool ortools of the percussive type. Any suitable cutting appliances may be employed, but herein therevis' utilized a reciprocatory cutting tool associated with a compressed air, direct-acting engine, the latter supplied with pressure fluid from a suitable source' (not shown) and having the cylinder 5 with its cooperating piston to which latter is connected the piston rod 6 and the cross head .7 (shown indotted lines Fig. 3).. The latterhas clamped thereto a suitable tool or tools such as the gang 8 of three channeling tools, the cutting ends of the latter being given} a reciprocatory cutting movement toward :and from the bot' tom of the channel groove as the engine piston is reciprocated. ,The. cross head 7 re- 7 justable as a unit towardor from the work.

'The sliding actuator frame, which in-. cludes the tool actuating engine and cross head guides, together with the, supported cross head and attached tools, is guided during its sliding movement upon a standard or intermediate support 11, which latter presents finished webs or guide ways 12- (Figs. 3 and 7 )to receive the inner finished face of the frame, gibs'13 beingsecuredto the frame to'overlie the inner edges of the said webs and retain the sliding frame thereon.

Thestandard or intermediate support 11 is secured to a swinging carrier or oscillatory frame 145, by connections which herein permit, when desired, of a periodic 'move'- ment by the standard audits cutting appliances toward and from the work. The

swinging carrier may be held fixed during the cutting operation or be given a swinging movement to swing the cutting appliances lengthwise the channel groove as well. In the illustrated form of machine the oscillatory frame consists of a plate circular in. form and supported at the active or cutting side of the truck. The intermediate support or standard is guided for sliding movement along the said frame 1 1 by means of the overlying gibs 15 which extend across the plate and are bolted thereto. These gibs overlie finished webs 16 on the standard and abut against raised shouldered portions 117 on the plate so that the standard is kept in a secure alinement at all times, being movable toward or from the work, under certain conditions, by devices which will be more fully described.

To provide for the swinging movement of the standard and the tool actuating devices lengthwise the channel groove when the machine is employed for'corner cutting, wall cutting, or the like, the plate 14 is mounted to swing through any desired are on the main supporting frame 17, which latter is mounted at the side of the machine as shown in Fig. 3. The plate 1a (see Fig. 3) has the centrally formed trunnion 18 j ournaled in a bearing block 19, the latter bolted to the frame 17. The trunnion has a tapered seat in the said bearing so that the plate may be adjustable in its bearing, the plate being held in position by means of the cap 20 fastened to the trunnion by the bolt 21 and prevented from turning thereon by the pin 22.

For angle cutting the main frame support 17 has a swinging adjustment about an axis lengthwise the channel groove, there being provided for this purpose (Fig. 3) at its back brackets 23 by which it may be fixedly and adjustably clamped to the trunnion shaft 2-1, the latter fixedly held at its end of the carriage frame 1 by the cap pieces 125.

The supporting frame 17 is held during cutting at any desired inclination by means of the inclined brace rods 25 which latter have a swivel connection each at its upper end to a lug 26 on the back of the main frame 17 and, at its lower end,is connected to a sleeved bracket 27 adjustably bolted toa seat upon the main frame 1. The lower end of the threaded brace rod passes entirely through the sleeve of the bracket and is secured thereto by means of check nuts 28, so that its length may be adjusted to permit the desired inclination of the supporting frame.

For swinging the carrier and the cutting appliances during corner cutting, the circumferential edge walls of the oscillating plate overlie the circumferential edge of the main support and the overlying part of the plate is provided with gibs 29, the latter frames so that the plate may be turned upon its central trunnion through any desired angle while held securely guided and alined by means of the frame.

Any suitable means may be provided for reciprocatively swinging the cutting appliances, but herein the swinging plate is turned through direct engagement of a driving member with the circumferential edge thereof, such driving member in the present case consisting of a flexible cable chain 30 (Fig. 1) passing over and about the uppermost half of the plate. The flanged edge of the latter is preferably grooved and toothed (Fig. 7) to receive the cable chain so that the plate constitutes, in effect, a large sprocket wheel. At each side of the plate the driving chain passes down and about the guide sprocket wheel 31 journaled upon the trunnion shaft, thence up and over the inter mediate idle sprocket wheel 32 journaled at each end of the carriage 1, and thence to the somewhat inclined sprocket wheel 33, the latter j ournaled upon a bracket 34: clamped on to each rail corner of the machine. From the guiding sprocket wheels 33 the chain passes downward (Fig. 6) at the rear of the machine and to the under side of the two idle uide sheaves 35 and thence to the upper side of the two toothed driving sprocket wheels 36, the latter carried by and fixedly secured to the end of the driving axles 2.

Each of the driving sprocket wheels 36, as shown in Fig. 7, is mounted to turn freely upon a reduced end of the axle, but is pro vided with a cone-shaped friction portion 37 adapted to engage the correspondingly shaped walls of the adjacent truck wheel 3. On the end of the axle there is keyed a coneshaped washer 38 adapted to seat in the outer face of the sprocket wheel, and there is also provided the clamping nut 39 by means of which the sprocket wheel may be forced into frictional engagement with the truck wheel, this serving to clamp the sprocket wheel to the axle or free the same therefrom so. as operatively to connect the driving chain 30 to or disconnect the same from the driving axles. Between the driving sprocket wheels 36 there is an intermediate guiding sprocket wheel 40 under which the chain passes so that the latter is held in good contact with the upper side of the driving sprocket Wheels 36. When the truck driving mechanism is operated and the truck axles turned, the chain may be driven from the driving sprocket wheels 36 and the cutting appliances caused to swing through the arc of a circle.

Suitable means may be employed for tightening or loosening the driving chain, the same being herein provided for by changing the position of one or more of the idle or guiding sprocket wheels, as for example, the sprocket wheels 32, which for this purpose are adjustably clamped in an elongated slot 45 in the machine frame 1 by means of the clamping stud 46.

Obviously other means for swinging the tools may be employed, if desired, the selected form of apparatus being herein shown for the purposes of illustration merely.

Any suitable means may be employed for imparting driving movement to the aXles, but herein 1 have shown a fluid pressure engine 4:? (Fig. 7) provided with a Cylinder l8 and connected to turn a transverse driving shaft 49. The latter carries at its end the beveled pinion which imparts equal. but opposite rotation to the two beveled gears 51 and 52. These may be separately clutched to or unclutched from the clutching shaft 53 by the sliding movement of the double clutch member-5 l54. .The movement of the latter is effected through the pair of yoke-shaped arms 55 each embracing a circumferential groove of its corresponding clutch member 54 and being pinned or otherwise secured to the reversing, sliding rod 56 which is mounted on brackets upon the carriage frame for sliding movement parallel with the clutch shaft 53. In one position the rod clutches the gear 51 to the clutch shaft to turn the latter in one direction, but, when shifted to its opposite position, it clutches the gear 52 to the said shaft to turn the latter reversely.

The carriage may be traversed with the cutting appliances held at a fixed position on the support for the ordinary channel cut, or may be traversed, if desired, while the cutting appliances are undergoing swinging movement, the necessary traversing movement in either case being imparted to the carriage through the clutch shaft 53. For this purpose the latter carries at each end a worm 57, the latter meshing (Fig. 3) with an underlying worm gear 58 geared or otherwise secured to the carriage axle 2. The carriage therefore may be moved under its own power in either direction according to the position of the clutch 54:.

7 In order to provide positive driving means for advancing the truck when the tools are ield at an extreme forward inclination, or to provide, when desired, against slippage due to any other cause, toothed or other positive driving connections are preferably employed between the truck and the guid- "ing rails. Herein such connections are pro vided by forming teeth upon the truck wheels adapted to engage the teeth of a rack formed in the rails, or otherwise presented by the trackway. For this purpose one side of the face of one or both sets of rails is provided with appropriately formed teeth 59 this purpose any suitable means may be provided. Herein for this purpose each front corner of the frame is provided (Fig. l)

with a bracket 61 having a depending por- 1 -t1on provided with in-turned gripplng fingers 62 adapted to underlie the flanges on the rails. The depending portion is threaded for engagement with the lower portion of a combined jack and binding screw 63, the latter having an upper portion 6%. a dapt ed to be gripped between the bracket and the truck frame when the clamp screw 65 is tightened, the upper portion of the bracket (as seen in Fig. 1) comprising half only of the socket for the screw. The rear corners of the machine also are provided with similar depending gripping fingers 62 (Fig. 3) and binding screws 63, these being carried by the bracket 84. The bracket 34: .is split where it receives the upper portion 64a of the screw, and the clamping bolt 66 is provided for clamping the same about the screw. During the travel of the carriage, the screws being withdrawn out of contact with the rails, the truck rests upon its wheels and the gripping fingers lie below the rail flanges. lVhen it is desired to fixedly position the machine upon the trackway, the screws 63 may be turned down to engage the rails, lifting the wheels free therefrom and causing the gripping fingers 62 to grip the rail flanges and hold the machine fast to the rails against displacement therefrom.

Duringcircular cutting the engine 47 operates to swing the standard of the tool through the arc of a circle simultaneously with the rapid percussive action of the tool. Then the swinging movement has advanced far enough in one direction the reversing rod 56 may be shifted and the swinging movement reversed. WVhile automatic means may be provided for such purpose, herein the rod 1s shifted by means of the upright a sleeve 71 pinned or otherwise-secured to the reversing rod so that movement of the hand lever shifts the latter. 2

As already referred to, the actuator frame 15 provided with a feedlng ad ustment to, ward or away from the work. For this purpose there is provided the usual feed screw 7 2 passingthrough the arched portion 73 of the standard and suitably held therein against longitudinal movement while'free to be turnedby a ratchet lever 7 4.. The lower end of the feed screw has threaded engagement with a split nut 75 (see Figs. 8 and 7) on the actuation frame so that the turning of the screw is adapted adjustably to feed the engine and cutting tools to or from the work.

A second. or double adjustment is secured by making the standard adjustalfile on and relatively to the swinging carrier so that a greatly increased length of cut may be arranged without changin the gang of tools. For thispurpose, connection between the standard and the swinging oarv is had by means oil a second or auxi iary ieed screw 76,- which also passes through the arched portion 73 of the standard and is held therein fixedly against longitudinal movement. At its lower end the feed screw 76 has threaded engagement with a nut 7'? carried by a part attached to the swinging c. rrier as will be more fully describer. The feed screw 76 may be adjustably turned by any desired means, the same ratchet lever 7 being here used for moving both feed screws 72 and 76. For this purpose the upper end oi the feed screw 76 has fixed thereto the gear 78 meshing with a gear 79 carried by the ratchet sleeve 80, which latter is controlled by' ratchet handle 7%. The particular construction o1 the ratchet, however, forms no essential part of the present invention and need not be further described since any suitable means may be used for turning the two adjusting screws either independently or together.

he described machine may be caused to travel along a trackway and, with the stand ard held fixed in an upright position or at some fixed inclination relatively to the worlr, may be employed to cut the ordinary channel groove in the open. ()n the other hand it may be clamped fast to the rails, as described, and, by turning the swinging carrier through the driving connections described, the cutting appliances may be given a swinging movement so that the tools are caused to act percussively along the arc of. the circle and perpendicularly to the bot tom oi the channel groove. For example, referring to Fig. 2, the machine may be clamped in the full line position shown and the tool gang caused to make successive channel cuts in the stone along the arcs a Z), a etc.

If an arc-shaped channel out is made in cutting the corner of a channel groove under the overlying side wall of a quarry, as the cut deepens, tools of greater length must be employed and, to carry the cut down for the necessary depth and in under the overhanging wall for the necessary reach, tool gangs must frequently be employed of such unwieldly mass to make them highly objectionable and render the cutting of the machine inellicient.

In the present machine, therefore, I have provided means for imparting to the cutting appliances simultaneously with their periodic swinging movement also a synchronous periodic advancing and receding move ment relative to the work, so that the resultant movement is a compound linear and swinging movement resulting in materially extending the line of cut and the reach oi the tools.

This may be accomplished by various mechanisms, but herein such a result is cured by advancing and retracting the cut ting appliances on the swinging carrier, such movement being preferably so timed with reference to the swinging movement oi the carrier that the cutting appliances are projected to the maximum extent at the extreme forward end of the swinging movement and are fully retracted at the end oi the back swing. To secure this periodic projection and retraction of the cut ing appliances, connections are provided for the standard so that the latter is advanced or retracted along the gibbed ways upon the swinging carrier as the latter is turned back and forth about its trunnion.

This may be accomplished in a variety o5 ways, but herein the nut 77 with which the feed screw 76 is engaged is carried by a sliding shoe 81 having (Fig. 7) finished webs S2 slidably mounted in suitable grooves 8 formed in the walls of the swinging carrier 14. To reciprocate the sliding shoe and thereby the standard, the former is connected by the link or connecting rod 8% to a crank arm 85. The latter, in turn, is secured to the face of a gear 86, herein elliptical in form and journaled upon a stud. 87. The elliptical gear 86 is arranged to mesh with the teeth of an appropriately termed rack 88, the latter carried by the swinging or oscillatory plate lt. As the plate reciprocatively swings it turns the elliptical gear about the journaling stud 87 and causes the reciprocatory advance and retraction of the shoe 81 and the standard 11 with its attached cutting appliances.

This movement of the cutting appliances materially extends the line of cut and the amount of work done by the machine for each swing of the carrier. For example, ferring to Fig. 2, and considering the 1" achine clamped to the rails, if periodic vance and retraction of the standard is provided in connection with the swinging movement of the carrier, the line of cut, instead of being along a b is along the are a c and ttlOZlg the are a 0 instead of along the are a Referring to Figs. 1 and 3, it will be seen that the journaling stud 87 for the elliptical gear is fixedly attached to an intermediate, adjustable member, herein comprising the feed plate 88*, mounted to turn about a hub 89 formed by the main support 17 The feed plate is provided with a clamping bolt 90 passing throughan aperture in the frame and having threaded engagement with a nut 91 which is movably contained within. a T- slot 92 formed in the opposing face of the feed plate. At its opposite (herein the bottom) end the feed plate, (Fig. 1) is provided with an arc-shaped slot 98 through which passes, with suitable clearance, (see Fig. 8) the end of a stud 94b carried by and fixedly secured to the oscillating plate'l.

- hen it is desired to dispense with the swinging movement and utilize the machine with the cutting appliances working at a fixed inclination, not only is'the feed: plate clamped to the main frame 17 by means of the clamping bolt and its nnt'91, but it is also clamped tightly to the swinging platel l by means of the stud 94 and its clamping bolt 95, thereby locking the main frame, the feed plate and the carrier all together and in fixed position and preventing the movement of the sliding shoe 81. On the other hand, if it is desired to utilize the swinging movement of the carrier alone, without the linear movement of the standard, the feed plate may be clamped to the carrier and unclamped from the frame 17 so that the feed plate will operate with the carrier and without movement of the elliptical gear or the connecting rod 84;.

The utility of the apparatus described is not limited to channel cutting in the bottom of the quarry, but the described machine may be employed for other purposes such as channel cutting in a vertical wall. For this purpose the main frame is pro vided with additional apertures 96 and 97 (Fig. 1) so positioned that the carrier with the standard and associated parts and the feed plate may be shifted through ap proximately 90 in either direction, and the feed plate clamped thereat'by inserting the clamping bolt 90 through the apertures 96 or 97, the cutting appliances being then presented horizontally at one end of the machine or the other, instead of vertically, and being adapted to carry the line of cut into a vertical wall in just the same manner as described with reference to the quarry bottom in connection with the diagram of Fig. 2.

The described machine can be utilized to elongate still further the line of cut and increase the reach of the cutting tools by causingthe machine itself periodically to advance and return synchronously with the swinging movement of the tool carrier. Under these conditions jack screws for lifting the machine are not, employed but the machine is allowed to rest upon the trackway and free to travel along the same.

When the machine is jacked up free from.

the rails and the carrier is given its swing scribed, as soon as the swinging movement is initiated, the machine also starts ahead and travels in that direction toward which the tools are swung.

Referring to Fig. 2, the movement of the machine under such conditions will be readily understood. Starting from the full line position shown, the machine will travel toward the dotted line position, the tool or cutting axis passing successively through the positions indicated by the oblique lines. hen the swinging movement of the tool carrier reaches its limit and is reversed, the traversing movement of the machine also reverses, and the machine and cutting appliances are returned to the full line posi tion shown, to start a fresh cut. a

The described traversing movement of the machinemay be used in conjunction with the swinging movement of the tool, either with or without the correspondingly timed reciprocatory linear movement of the standard, Ineither case the capacity of the machine to reach in under the oblique side wall of the quarry is considerably increased. When employed in conjunction with such linear movement of the standard, the line of cut will be seen to be, greatly extended and the capacity of the machine greatly increased for each swing of the tool. For example, referring to Fig. 2, if the tool is adapted to out along the are a Z) when swinging from a fixed center, then with the combined linear, synchronous movement of the standard and the synchronous movement of the machine itself, the cut takes place along the line a (Z providing a gain,

perhaps 150% for that particular level of cut. At the next level the out, instead of taking place along the line a Z) takes place along the line a d. By this compound movement the machine can be utilized to cut a corner of maximum obliquity with a minimum tool length.

By appropriately propor-tioning these movements, the flattening or straightening of the curved line of cut can be carried to any desired extent according to the angle at which it is required to do the cutting. In soft stone or coal the bottom of the cut might be kept almost straight. hard stone the tool can be made to strike the bottom of the cut. at an angle of. consi-derable obliquity without materially. diminishing the efliciencyof the machine, since the tool does not glance off from'the rock until an angle of approximately 26 is reached. i

ing machine and still more specifically in a stone channeling machine intended for Even in I corner cutting, I believe that in many respects the movements of the cutting apphances and the mechanism for providing such movements are broadly new and are applicable to machines of widely different construction and intended for different purposes, all of which are within the scope of this invention.

Furthermore, while I have described in detail, for illustrative purposes, the construction of one specific form of machine, it is to be understood that the invention is not limited to the form or relative arrangement of parts or the details of construction, or the specific application made herein thereof, but that extensive deviations may be made from the illustrated embodiment of the invention without departing from the spirit thereof.
